10 Bottle Value COA and batch testing paperwork

I opened the site before coffee. Four listings, all 10 ml bottles: Alpha, Beta, Gamma, Delta. Lot codes read BV-2401 through BV-2404. I copied them from the cart page, so double-check the labels.

COAs? Only two of the four batches have public PDFs. Both show lab name and method, but one lacks a clear date. The other two say pending. That is where I stopped.

Pending COAs are just vibes with a logo. Not enough for me.

Pricing is per unit. The site shows a 10-bottle tier discount at checkout. VAT appeared for Latvia, and shipping was calculated by destination. Not included. I did not finish checkout.

Shipping to UK quoted tracked at cart. No free threshold. VAT added before shipping. I saw 21 percent line. Could be destination-dependent.

Batch BV-2403 has a third-party COA with lab, HPLC method, and date. BV-2404 only has a screenshot, no method. That gap matters more than the price.

I emailed them. They claim all four batches have COAs, but only two are public. Lab is in Poland, method HPLC-UV, dates from Feb 2024. I asked for lot-specific PDFs.

So two public, two behind email. Yellow flag, not red. Depends if they send the full PDF today.

Bulk tiers: 1-4 full price, 5-9 ten percent off, 10+ fifteen percent. Shipping still calculated. No mention taxes included. I would ask for lot-specific COA before ordering.

New angle: ask whether those COAs are purity-only or full-panel. Many labs run HPLC purity but skip sterility, endotoxin, and heavy metals; for a 10-vial order I’d want the lab’s sample receipt date and a lot number that matches the vial label, not just the site. Also, does the 10+ tier require a single batch, or can it mix lots? That matters to me more than the discount—I weigh daily but only act on my 10-day trend, so supply ambiguity just adds noise.

Budget student here: emailing for COAs is my vrsion of a group project—nobody wants to do it 😅

New angle: ask for a photo of the actual vial label next to the COA page, so you can eyeball that the lot ID matches exactly. A “batch COA” that doesn’t tie to the specific lot is just nice stationery. I regained most of what I lost, so now I keep a boring note: lot, COA date, shipping time, how I feel, weekly wight trend. Two weeks of that tells me more than a pretty PDF. If they won’t show the vial/COA match, that’s my personal red line.

Ha, emailing for COAs is the real group project. If the lot # doesn't match, it's just a pretty PDF.
